Good morning :)
#151 Yes I am customizing the font so thats its unique. On #129, the font is Handel Gothic, very clean with a bit of a tech feel.
1. the url is helvetica medium and I it can come up a touch bigger. Also at smaller sizes the url can be resized. I will show you that in a few moments.
I like the flat bottom because it sits nicely in the slot between the "k" and the last "s" and is slightly off center. I'm really trying to ride the fence between the cloud and print. I tried a few of them and the rounded bottom pushed it more heavily to the print and the I started to lose the iconic cloud feel. Except for the color it looked more like a print with the lines being so strong.
Clouds can have a flat base, thumbprints generally don't so it helped bring it back to a cloud. That was my thinking.
Posting a couple of updates in a few moments.
